How to Read a U-100 Insulin Syringe
1
Find the unit markings
Each line on the barrel is units. Major marks at 10, 20, 30 up to 100. Minor marks every 2 units.
2
Draw to the correct line
Pull the plunger until the rubber stopper aligns with your target unit number.
3
Units ≠ mg ≠ mcg
Units measure volume, not mass. The calculator converts your mcg dose to units based on concentration.
4
Small dose = tiny volume
250mcg at 2500mcg/mL = 10 units. If under 5 units, add more BAC water to make measuring easier.
